SmartWare Software Configuration Guide 40 • Call router configuration

Let’s examine the mechanism of mapping tables in more detail. Figure 65 shows three mapping tables and a call that is routed through this mapping table. The call contains various call properties that are examined and modified by the mapping tables:

Example #1

Figure 65. Mapping table examples

Example #1: This example shows a mapping table that selects the best matching entry based on the called party number of a call and, once found, sets the called party URI. In the example a call arrives to the mapping table with a called party number of 201. The mapping table selects the first entry, which matches best, and sets the called party URI of the call to sip:john.smith@nil.net.

Example #2: This example shows a mapping table that selects the best matching entry based on the presenta- tion indicator and, once found, sets the called party number. In the example a call arrives to the mapping table with a presentation indicator of restricted. The mapping table selects the only entry (which matches) and sets the called party number to the empty string.

Example #3: This example shows a mapping table that selects the best matching entry based on the called party number and, once found, changes the same property, the called party number. This is a very powerful method to manipulate numbers using regular expressions. In this example a call arrives to the mapping table with a called party number of 234. The mapping table selects the only entry (which matches) and adds a prefix of 5551 to the called party number.
